Current Excitation Supply Current Loop Converters
from Dataforth Corporation
Each DSCA42 2-wire transmitter interface module provides a single channel of 4 to 20mA process current input which is filtered, isolated, amplified, and converted to a high-level voltage output. An isolated 24V power supply is provided to power the 2-wire transmitter. Signal filtering is... [See More]

from Time Mark Corporation
Liquid level controllers generally require a 4-20mA loop current that represents zero to 34.6 feet. The loop current indicates the level of liquid in a tank or reservoir, and is usually generated by an expensive pressure transducer or ultrasonic sensor. If you already have a tank with float switches... [See More]
